 Five specimens. Top left, Dactylioceras commune from Yorkshire. Nice specimen approx. 70mm diam, much smaller specimen with crushed centre on the back. Top right, nice single yellow calcite Promicroceras from Lyme Regis (25mm diam). Bottom left, small ammonite in Birchi bed, I think it is the smooth centre of a Microderoceras, 15mm diam (will prepare easily). Bottom centre, small white Promicroceras approx. 20mm. Bottom right small block of popcorn stone. Contains at least one small Microderoceras and four or five Promicroceras. This stone is relatively easy to prepare. Largest ammonites approx. 12mm. Will be pretty when prepared.

Moderate Difficulty.
